Description

Technical Field

[0001] The present application relates to the technical field of printed paper production, and in particular to a printed paper production cutting device and cutting process. Background Art

[0002] In recent years, with the development of digital printing technology, office automation and personal computers, the use of printing paper has increased day by day, and the production equipment and processes of printing paper have been continuously optimized.

[0003] During the paper production process, when the pulp is rolled into paper strips, a reel is usually used to reel the paper strips, and then the paper strips are transported to the paper processing plant for cutting. Traditionally, paper cutting is carried out by using a hydraulic cylinder fixed on a frame to drive a cutting knife to cut the paper on the conveyor belt, so that the paper strips are divided into the required size for printing paper. However, when the cutting knife cuts the paper, the paper needs to stop moving. This stoppage during paper cutting increases the time of the entire paper cutting process, thereby reducing the efficiency of paper cutting. Summary of the Invention

[0004] In order to improve the problem of low paper cutting efficiency caused by paper being stationary during cutting, the present application provides a printing paper production cutting device and a cutting process.

[0005] On the one hand, the present application provides a printing paper production and cutting device adopting the following technical solution:

[0006] A printing paper production and cutting device includes a frame and a cutting knife, wherein the frame is provided with a first conveying mechanism for conveying paper, the frame is provided with a second conveying mechanism for conveying cut paper, the frame is provided with a cutting mechanism for driving the cutting knife to cut paper, the frame is provided with a guide mechanism for sliding the cutting mechanism, the frame is provided with a driving mechanism for driving the cutting mechanism to slide along the guide mechanism, and the sliding speed of the cutting mechanism along the guide mechanism is the same as the moving speed of the paper.

[0007] By adopting the above technical solution, when cutting paper, several sheets of paper are first stacked on the first conveying mechanism, and then the first conveying mechanism drives the paper to move, and then the driving mechanism drives the cutting mechanism to slide along the guide mechanism, and the cutting mechanism slides above the paper, and the cutting mechanism and the paper slide at the same speed, so the cutting mechanism and the paper remain stationary, and then the cutting mechanism drives the cutting knife to move toward the paper and cut it. The cut paper is transported by the second conveying mechanism, thereby effectively avoiding the need for the paper to remain stationary during cutting, thereby reducing the paper cutting time and improving the paper cutting efficiency.

[0008] In a specific possible implementation scheme, the cutting mechanism includes a support plate and a hydraulic cylinder. The support plate is arranged on the guide mechanism and slides along the guide mechanism. The hydraulic cylinder is arranged on the support plate. The cutting knife is arranged at the piston rod end of the hydraulic cylinder. A cutting plate for squeezing the cutting knife is provided on the frame, and the cutting plate is located between the first conveying mechanism and the second conveying mechanism.

[0009] By adopting the above technical solution, when cutting paper, the driving mechanism drives the support plate to slide on the guide mechanism, and then the hydraulic cylinder extends, and the hydraulic cylinder drives the cutting knife to cut toward the paper. The cutting knife extends to the cutting plate and cuts the paper. Then, the cut paper moves along with the second conveying mechanism, thereby realizing the cutting and transportation of the paper.

[0010] In a specific possible implementation scheme, an extrusion plate is provided at the end of the piston rod of the hydraulic cylinder, two groups of extrusion rods are slidably provided on the extrusion plate, the cutting knife is located between the two groups of extrusion rods, each group of the extrusion rods is provided with a push plate for squeezing paper, and each of the extrusion rods is provided with an extrusion spring, which is used to push the extrusion plate to squeeze the paper.

[0011] By adopting the above technical solution, when the hydraulic cylinder drives the cutting knife to cut the paper, the hydraulic cylinder extends toward the paper. At this time, the hydraulic cylinder drives the extrusion plate and the push plate to move toward the paper. Before the cutting knife contacts the paper, the push plate contacts the paper. As the hydraulic cylinder continues to extend, the extrusion plate squeezes the extrusion spring to contract. At this time, the extrusion spring pushes the push plate to squeeze the paper, thereby improving the stability of the paper during cutting and improving the paper cutting effect.

[0012] In a specific embodiment, the first conveying mechanism includes a conveyor belt, a driving roller, a driven roller, and a conveying motor, wherein the driving roller and the driven roller are both rotatably arranged with the frame, the output shaft of the conveying motor is coaxially arranged with the driving roller, and the driving roller and the driven roller are connected by the conveyor belt;

[0013] The driving mechanism includes a driving sprocket, a driven sprocket and a chain. The driving sprocket and the driven sprocket are both rotatably arranged with the frame. The driving roller and the driving sprocket are driven by a transmission pair, and the support plate is arranged on the chain.

[0014] By adopting the above technical solution, when transporting paper, the paper is first placed on the conveyor belt, and then the conveyor motor is driven to rotate. The conveyor motor drives the conveyor belt to rotate through the active roller, thereby realizing the transportation of the paper. At the same time, the active roller drives the active sprocket to rotate through the transmission pair, the active sprocket drives the chain to rotate through the driven sprocket, and the chain drives the hydraulic cylinder to rotate through the support plate, thereby achieving consistency and coordination of the movement of the paper and the cutting knife.

[0015] In a specific possible implementation scheme, the guide mechanism includes a guide support plate arranged on the frame, a linear slide and a guide slide are provided on the guide support plate, a reinforcement block for sliding in the linear slide and a slider sliding in the guide slide are provided on the support plate, and the linear slide is located above the cutting plate.

[0016] By adopting the above technical solution, when the chain drives the support plate to slide, the reinforcement block on the support plate slides on the guide support plate along the linear slide groove. The reinforcement block can increase the contact area between the support plate and the linear slide groove, thereby making the cutting knife more stable when cutting paper. When the support plate is reversing, the reinforcement block slides out of the linear slide groove and the slider always slides in the guide slide groove, thereby making the support plate slide more smoothly.

[0017] In a specific possible implementation scheme, a plurality of rolling wheels are rotatably provided on the guide support plate, the axes of the plurality of rolling wheels are parallel to each other, each of the rolling wheels extends into the linear slide groove, and the cutting knife cuts the paper so that the reinforcement block conflicts with the rolling wheel.

[0018] By adopting the above technical solution, when the reinforcing plate slides in the linear slide groove, the cutting knife cuts the paper. At this time, the reinforcing plate contacts the rolling wheel, so that the sliding friction between the reinforcing plate and the linear slide groove is converted into rolling friction, thereby reducing the friction force on the reinforcing plate when the cutting knife cuts the paper.

[0019] In a specific possible implementation scheme, the second transmission mechanism includes a driving motor, a driving shaft, a driven shaft and a conveyor belt. The driving shaft and the driven shaft are both rotatably arranged with the frame. The output shaft of the driving motor is coaxially arranged with the driving shaft, and the driving shaft and the driven shaft are connected by the conveyor belt.

[0020] By adopting the above technical solution, when the paper cutting is completed, the drive motor is started, the drive motor drives the driving shaft to rotate, and the driving shaft drives the conveyor belt to rotate through the driven shaft to realize the transportation of the cut paper.

[0021] In a specific possible implementation scheme, a drive chain is slidingly provided on the frame, a transport plate for receiving the paper on the conveyor belt is provided on the drive chain, the transport plate and the drive chain are intermittently connected to the drive chain through a connecting piece, a baffle for limiting the sliding of the paper is provided on the frame, two sorting plates for squeezing the paper are slidingly provided on the frame, the paper is located between the two sorting plates, and a lifting member for driving the baffle to rise and fall is provided on the frame.

[0022] By adopting the above technical solution, the paper moves with the conveyor belt and slides onto the transport plate. The drive chain drives the transport plate to slide. When the paper is blocked by the baffle, the transport plate slides relative to the drive chain through the connecting piece. Then, the two sorting plates are used to sort the two sides of the paper to make the paper more neat. Then, the baffle is raised by the lifting piece. At this time, the drive chain drives the transport plate to move through the connecting piece to realize the transportation of the paper.

[0023] In a specific possible implementation scheme, the connecting member includes a sprocket, a clamping rod, a driving rod and an engaging spring, the sprocket is engaged with the driving chain, the sprocket is arranged on the clamping rod, the clamping rod is slidingly arranged with the transport plate, the driving rod and the clamping rod are connected by a connecting rod, the engaging spring is used to squeeze the sprocket to engage with the driving chain, and the driving rod squeezes the baffle to disengage the sprocket from the driving chain.

[0024] By adopting the above technical solution, when the transport plate contacts the baffle, the baffle squeezes the drive rod to slide, and the drive rod drives the card rod to slide through the connecting rod, and the card rod drives the chain teeth to disengage from the drive chain. At this time, the engaging spring contracts, thereby realizing the relative sliding of the transport plate and the drive chain. When the baffle rises, the engaging spring pushes the chain teeth to engage with the drive chain through the engaging spring, and the drive chain can drive the transport plate to move.

[0025] On the other hand, the present application provides a printing paper production and cutting process using the following technical solutions:

[0026] A printing paper production and cutting process comprises the following steps: S1: unloading paper, unwinding the paper from a roll;

[0027] S2: stacking, stacking the papers on the multiple rolls on the first conveying mechanism in sequence;

[0028] S3: Cutting, the driving component drives the cutting knife to cut the paper through the cutting component;

[0029] S4: neat, the cut paper is squeezed flush with the finishing plate through the baffle.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. When cutting paper, several sheets of paper are first stacked on the first conveyor mechanism, and then the first conveyor mechanism drives the paper to move. Then the driving mechanism drives the cutting mechanism to slide along the guide mechanism. The cutting mechanism slides above the paper, and the cutting mechanism and the paper slide at the same speed, so the cutting mechanism and the paper remain stationary. Then the cutting mechanism drives the cutting blade to move toward the paper and cut it. The cut paper is transported by the second conveyor mechanism, which effectively avoids the need for the paper to remain stationary during cutting, thereby reducing the paper cutting time and improving the paper cutting efficiency.

[0032] 2. After the paper is cut, it is transported to the transport board through the conveyor belt, and then the side of the paper is squeezed by the baffle and two sorting plates, so that the cut paper can be stacked more neatly. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The following is combined with Figure 1-7 This application is described in further detail.

[0042] On the one hand, an embodiment of the present application discloses a printing paper production and cutting device.

[0043] Reference Figure 1 、 Figure 2 A printing paper production and cutting device includes a frame 1 and a cutting knife 11. The frame 1 is provided with a plurality of reels 12 that are rotatable. The reels 12 are wound with paper tapes. The frame 1 is provided with a plurality of rollers that stack the paper tapes on the plurality of reels 12 up and down to form a paper tape with a certain thickness. The frame 1 is provided with a first conveying mechanism 2, which includes a conveyor belt 21, an active roller 22, a driven roller 23, and a conveying motor 24. The active roller 22, the driven roller 23 and the frame 1 are all rotatable. The output shaft of the conveying motor 24 is fixedly arranged coaxially with the active roller 22. The conveyor belt 21 passes around the active roller 22 and the driven roller 23. The movable roller 23 is tightened, the paper tape extends from the drum and is placed on the conveyor belt 21. The frame 1 is provided with a second conveying mechanism 3, a cutting mechanism 4, a driving mechanism 5 and a guide mechanism 6. The cutting knife 11 is arranged on the cutting mechanism 4. A cutting plate 13 is fixedly provided on the frame 1. The cutting plate 13 is located between the conveyor belt 21 and the second conveying mechanism 3. The driving mechanism 5 is connected to the conveyor belt 21 through a transmission pair 14. The driving mechanism 5 drives the cutting mechanism 4 to slide along the guide mechanism 6. The speed at which the cutting mechanism 4 slides on the guide mechanism 6 is the same as the speed at which the paper tape moves on the conveyor belt 21 and the speed at which the paper tape moves on the reel.

[0044] When cutting printed paper, the reel 12 wrapped with paper tape is first placed on the frame 1, and then the paper tape is unwound from the reel 12 by the roller, and then the paper tape on each reel 12 is stacked on each other to form paper of a certain thickness, and then the conveying motor 24 is started, and the conveying motor 24 drives the active roller 22 to rotate, and the active roller 22 drives the conveyor belt 21 through the driven roller 23. At the same time, the conveyor belt 21 drives the driving mechanism 5 to move through the transmission pair 14, and the driving mechanism 5 drives the cutting mechanism 4 to move along the guide mechanism 6. The cutting mechanism 4 drives the cutting knife 11 to move at the same speed as the conveyor belt 21 drives the paper to move, so that the cutting knife 11 and the paper remain relatively stationary, and then the cutting mechanism 4 drives the cutting knife 11 to cut the paper, and the paper after cutting is transported by the second conveying mechanism 3, thereby realizing the cutting of the paper, and at the same time, it can effectively avoid the time for the paper to stop for cutting, thereby improving the efficiency of paper cutting.

[0045] Reference Figure 2 、 Figure 3 and Figure 4 The driving mechanism 5 includes a driving sprocket 51, a driven sprocket 52 and a chain 53. The number of the driving sprocket 51, the driven sprocket 52 and the chain 53 is two. Each driving sprocket 51 is rotated with the frame 1 through a rotating shaft. The transmission pair 14 includes a transmission chain and sprockets coaxially arranged on the rotating shaft and the output shaft of the transmission motor. The two sprockets are driven by the transmission chain. The two driven sprockets 52 are rotated with the frame 1. A driving sprocket 51 and a driven sprocket 52 are connected by a chain 53. Then, the two chains 53 are arranged in parallel, and the cutting mechanism 4 includes a support plate 41 and a hydraulic cylinder 42. The support plate 41 is provided with a groove for inserting the chain 53. The chain pin of the chain 53 inserted into the groove extends axially on both sides and is inserted into the support plate 41 and fixed to the support plate 41. There are two hydraulic cylinders 42, and the cylinder bodies of the two hydraulic cylinders 42 are fixedly set on the side of the support plate 41 away from the chain 53. The piston rod ends of the two hydraulic cylinders 42 are jointly fixed with a mounting support 43, and the cutting knife 11 is installed on the mounting support 43.

[0046] Reference Figure 2 、 Figure 3 and Figure 4The cam 442 is provided with a plurality of springs 444 on the top of the cam 443, and the springs 445 are provided with a plurality of springs 446 on the bottom of the cam 443. The springs 446 are provided with a plurality of springs 447 on the top of the cam 443. The springs 447 are provided with a plurality of springs 448 on the bottom of the cam 443.

[0047] Reference Figure 2 、 Figure 3 and Figure 4 The guide mechanism 6 includes two sets of guide support plates 61, each of which is provided with a linear slide 621 and a guide slide 622. The guide slide 622 is divided into a straight segment and an arc end. The linear slide 621 is connected to the guide slide 622. The support plate 41 is provided with a reinforcement block 63 for sliding in the linear slide 621 and a slider 64 for sliding in the guide slide 622. The reinforcement block 63 in this embodiment is a rectangular block, and the slider 64 is a circular block. The slider 64 always slides in the guide slide 622. When the slider 64 slides to the guide slide 6 22, the reinforcing block 63 slides into the linear slide 621, and the guide support plate 61 is provided with a plurality of rolling wheels 65 on the linear slide 621 near the bottom. Each rolling wheel 65 is arranged to rotate in the length direction of the linear slide 621. The axial directions of each rolling wheel 65 are parallel to each other. Several rolling wheels 65 are arranged along the length direction of the linear slide 621. A through groove is provided on the side wall of the linear slide 621. The rolling wheel 65 passes through the through groove and extends into the linear slide 621. When the cutting knife 11 cuts the paper, the reinforcing block 63 squeezes the rolling wheel 65 and slides.

[0048] When cutting the paper, the conveying motor 24 drives the conveyor belt 21 to rotate and drives the driving sprocket 51 to rotate at the same time. The driving sprocket 51 drives the chain 53 to rotate through the driven sprocket 52, and the chain 53 drives the support plate 41 to rotate. At this time, the reinforcing block 63 on the support plate 41 slides along the linear slide 621, and the slider 64 slides along the guide slide 622. At the same time, the sliding speed of the support plate 41 is the same as the speed of the paper moving on the conveyor belt 21. Then the hydraulic cylinder 42 is driven to extend, and the piston rod of the hydraulic cylinder 42 drives the extrusion plate 441 and the cutting knife 11 to extend toward the paper. Then the push plates 445 on both sides first contact with the paper The paper comes into contact with the paper, and then as the hydraulic cylinder 42 extends, the extrusion spring 444 contracts and pushes the push plate 445 to press against the paper, and then the cutting knife 11 cuts the paper. The pushing plate 445 squeezes the two sides of the paper cutting position, which effectively prevents the paper from being scattered during cutting. At the same time, when the paper is cut, the force of the paper on the cutting knife 11 is upward, and then transmitted to the reinforcing block 63, so that the reinforcing block 63 comes into contact with the rolling wheel 65, and at the same time drives the rolling wheel 65 to rotate, so that the sliding friction between the reinforcing block 63 and the linear slide 621 is converted into rolling friction, thereby reducing the friction force on the reinforcing block 63.

[0049] After the paper cutting is completed, the hydraulic cylinder 42 contracts, and at this time the slider 64 on the support plate 41 slides into the guide slot 622, the reinforcement block 63 slides out of the linear slot 621, and then the chain 53 drives the support plate 41 to slide upward. At this time, another cutting knife 11 slides above the paper and cuts the paper. The support plate 41 moves circumferentially driven by the chain 53, so that the cutting knife 11 continuously cuts the paper.

[0050] Reference Figure 2 、 Figure 5 The second conveying mechanism 3 includes a driving motor 31, a driving shaft 32, a driven shaft 33 and a conveyor belt 34. The driving shaft 32 and the driven shaft 33 are rotatably arranged with the frame 1. The output shaft of the driving motor 31 is coaxially fixed with the driving shaft 32. The conveyor belt 34 passes around the driving shaft 32 and the driven shaft 33 and is tightened. The conveyor belt 34 is arranged along the sliding direction of the paper. The rotation speed of the conveyor belt 34 is greater than the moving speed of the conveyor belt 21. A slide bar 71 is provided on the frame 1. Several transport plates 72 are rotatably provided on the slide bar 71. A drive chain 73 is rotatably provided on the frame 1.

[0051] Reference Figure 5 、 Figure 6 and Figure 7When the cam 742 is in the unlock state, the cam 743 is unlocked, and the cam 744 is unlocked. 3 is inserted horizontally into the transport plate 72 and slidably arranged with the transport plate 72. One end of the driving rod 743 extends out of the transport plate 72, and the other end of the driving rod 743 extends into the rotating cavity 745. The driving rod 743 is hinged with a connecting rod 746 at the end extending into the rotating cavity 745. The other end of the connecting rod 746 is hinged to the clamping rod 742. The engaging spring 744 is sleeved on the clamping rod 742. One end of the engaging spring 744 is fixedly connected to the transport plate 72, and the other end of the engaging spring 744 is fixedly connected to the clamping rod 742. When the baffle 75 presses the driving rod 743, the driving rod 743 drives the clamping rod 742 to rise through the connecting rod 746, so that the sprocket 741 is disengaged from the driving chain 73.

[0052] Reference Figure 6 Two cylinders 77 are fixed on the baffle 75, and each cylinder 77 is provided with a sorting plate 78. The two sorting plates 78 are arranged opposite to each other, and the paper is located between the two sorting plates 78. The cylinder 77 pushes the sorting plates 78 to squeeze the stacked paper.

[0053] When the paper cutting is completed, the paper slides onto the conveyor belt 34. Due to the speed difference between the conveyor belt 34 and the conveyor belt 21, a certain distance is generated between the two adjacent piles of paper, and then the paper slides onto the transport plate 72. At this time, the sprocket 741 engages with the drive chain 73, and the drive chain 73 drives the transport plate 72 to move. Then the transport plate 72 moves to the baffle 75 and collides with the baffle 75. At this time, the baffle 75 squeezes the drive rod 743 so that the drive rod 743 retracts into the transport plate 72, and then the drive rod 743 drives the card rod 742 to rise through the connecting rod 746 so that the sprocket 741 is disengaged from the drive chain 73, and then the transport plate 72 stops sliding, and then the two cylinders 77 extend, and the cylinder 77 pushes the sorting plate 78 to squeeze the paper, making the two sides of the paper more neat, which is convenient for subsequent packaging.

[0054] When the paper is sorted, the two cylinders 77 contract, so that the two sorting plates 78 are separated from the paper, and then the baffle 75 is lifted by the lifting member 76. Then, the contact baffle 75 squeezes the drive rod 743, and the card rod 742 moves downward under the push of the engagement spring 744, so that the chain teeth 741 engage with the drive chain 73, so that the drive chain 73 can drive the transport plate 72 to move, thereby realizing the transportation of paper.

[0055] The implementation principle of a printed paper production cutting device and a cutting process in an embodiment of the present application is as follows: when cutting paper, several sheets of paper are first stacked on a first conveying mechanism 2, and then the paper is driven to move by the first conveying mechanism 2, and then the driving mechanism 5 drives the cutting mechanism 4 to slide along the guide mechanism 6, and the cutting mechanism 4 slides to the top of the paper, and the cutting mechanism 4 and the paper slide at the same speed, so the cutting mechanism 4 and the paper remain stationary, and then the cutting mechanism 4 drives the cutting knife 11 to move toward the paper and cut, and the cut paper is transported by the second conveying mechanism 3, thereby effectively avoiding the need for the paper to remain stationary during cutting, thereby reducing the paper cutting time and improving the paper cutting efficiency.

[0056] On the other hand, an embodiment of the present application discloses a printing paper production cutting process.

[0057] A printing paper production and cutting process comprises the following steps: S1: unloading paper, unwinding the paper from a roll 12;

[0058] S2: stacking, stacking the papers on the multiple rolls 12 on the first conveying mechanism 2 in sequence;

[0059] S3: Cutting: the driving assembly drives the cutting blade 11 to cut the paper through the cutting assembly;

[0060] S4: Tidying up, the cut paper is squeezed flush with the finishing plate 78 through the baffle 75.

[0061] In step S1 , a worker first hoists a plurality of reels 12 onto a frame 1 , then stacks the paper tapes on top of each other and places them on a drum.

[0062] In step S2 , the paper after being bent by the roller is placed on the conveyor belt 21 , and then the conveyor belt 21 and the roller drive the paper to move.

[0063] In step S3 , the chain 53 drives the cutter 11 to move at a speed the same as the paper movement speed, and then drives the hydraulic cylinder 42 to extend, and the hydraulic cylinder 42 drives the cutter 11 to cut the paper, and the cut paper moves along the conveyor belt 34 .

[0064] In step S4, the stacked papers after cutting are accelerated by the conveyor belt 34, and a gap exists between two adjacent stacks of papers. Then the papers slide onto the transport plate 72, the baffle 75 blocks the movement of the transport plate 72, and the cylinder 77 drives the sorting plate 78 to sort the papers.

[0065] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
